Different angle.
When my parents were sending the invites out for my Confirmation they said the dinner invitatin was a child free event. Because of my age, 13, most aunts and uncles had kids and some a lot younger than me but some older and with kids on their own, and it was a sit down event at my parents home. Now, my mum usually included children at all parties at our house, especially for Christmas as her philosophy is that "no party or family occasion is complete without children", but on THIS event she wanted it child free. My cousin ignored this and brough her 18 month old "unruly" daughter in pure spite (as she later confessed.) She let her daughter stuff her self with food to keep her quiet, puke it all up over the table, throw knives and forks, glasses smashed down on the floor, etc. When HER own firstborn had his Confirmation some 15 years down the line she realized with shame how stupid she had been and called my mum to apologise .....
Never mind what you think of child free people getting married, children, whatever age can cause a lot of trouble and upset as you cannot foresee everything that will happen.
When I went to my cousins wedding overseas I brought a friend to mind my then 20 month old son. She came down with a tummy bug and was zonked out in bed at the guest house. I took my son to the ceremony. When the priest said: "And do you X take Y... " My son shouted a loud "NO" and started running around. So I took him outside the church for the rest of the ceremony. I had to take him to the reception too. It was a stand up SUSHI event, with NO seats, so there was nowhwere to feed him, and nowhere for me to sit down. I said my good byes very quickly. It just simply wasnt suitable for a child, never mind a mother with a child in tow.
Good luck whatever you decide.
